There are two games on the Wii that I REALLY wanna run.

Resident Evil 4 and Metroid Prime 3 (or Metroid Prime Trilogy).

I'm running system menu v3.2U I used the Twilight Hack to softmod the Wii and install the HBC and the Gamma loader. I haven't downloaded either of the aforementioned games, but I've downloaded Super Mario Galaxy and Wario Land Shake It and gotten them to run.

If someone could tell me which IOS I'd need to play those two games, that'd be wonderful!

Resident Evil 4 is an old game, so that should work with no problem. Do a search on Metroid Prime Trilogy, you need to do a alt.dol boot method to get that working.
